Abstract

Visualization is an important means of understanding and explaining the natural phenomena. The visualization of ocean can help us understand and utilize the undersea world. As we know, the ocean is a real three-dimensional space, so the visualization includes not only the simulation of interface terrain (such as sea water surface, sea bottom, etc.) but also the hydrographic feature (such as salinity, temperature, pressure, current directions etc.). In this paper, taking the temperature field in the sea as the example, we discussed the visualization of data of space-fulfilled field from a viewpoint located in the field. We analyzed the acquisition and interpolation of 3-D oceanic data in section 2, proposed an Octree model in section 3, introduced visualization in scientific computing and implemented temperature field visualization based on volume rendering in section 4. Lastly, some conclusions are given in section 5.
